no. 1 Embodiment approach

[0040] figure 1 It is a figure which shows the structure of the navigation apparatus 10 when the map information processing apparatus concerning 1st Embodiment of this disclosure was applied to the navigation apparatus (NAVI) 10. The navigation device 10 determines whether or not the new road is a tunnel, and adds new road data to the map data. The navigation device 10 includes a global positioning system (GPS) receiver (GPS REC) 20, an autonomous navigation sensor (SELF-CONT NAVI SENS) 21, a storage device (STORAGE) 22, an operation switch group (SWITCH) 23, and a display device (DISPLAY) 24. Audio input and output device (AUDIO) 25, VICS (registered trademark) receiver (VICS REC) 26, control device (CONTROL) 30.

[0041] The GPS receiver 20 receives GPS signals transmitted from GPS satellites, and detects the absolute position and the absolute orientation of the vehicle. The current position of the vehicle detected by the GPS receiver 20 and the reception strength of the ...

no. 2 Embodiment approach

[0083] About the navigation device 10 which concerns on 2nd Embodiment, the point which differs from the navigation device 10 which concerns on 1st Embodiment is demonstrated. The navigation device 10 according to the second embodiment determines whether or not a new road is an underpassing road, and adds new road data to map data.

[0084] The determination unit 35 of the navigation device 10 according to the second embodiment stores the background information stored in the storage device 22 in the case where the travel trajectory data generated by the generation unit 34 includes data indicating that there is no GPS signal reception. The data is read out, and it is judged whether the driving track of the vehicle overlaps with the railway on the ground. Therefore, the determination unit 35 functions as an overlap determination unit.

[0085] Further, the attribute setting unit 36 ​​sets the underpass road attribute to the traveling trajectory data on the condition that the ve...

no. 3 Embodiment approach

[0102] About the navigation device 10 which concerns on 3rd Embodiment, the point which differs from the navigation device 10 which concerns on 1st Embodiment is demonstrated. The navigation device 10 according to the third embodiment determines whether or not a new road is an underpassing road, and adds new road data to map data.

[0103] The judging unit 35 of the navigation device 10 according to the third embodiment determines whether the traveling trajectory of the vehicle is downward when the traveling trajectory data generated by the generating unit 34 includes data indicating that there is no GPS signal reception. cross the road. Specifically, based on the heights of the start point and end point of the travel trajectory taken out from the road data stored in the storage device 22, and the gradient of the travel trajectory included in the travel trajectory data, it is determined whether the travel trajectory is an underpass. the way. Therefore, the determination unit...

Abstract

The map information processing device, in the event that the current position has deviated from a target street included in street data, generates driving route data for the vehicle in such a way as to include reception status data indicating whether or not there is GPS signal reception; in the event that the generated driving route data includes reception status data indicating that there is no GPS signal reception, determines on the basis of the map data whether the driving route passes through a high-rise building area; and in the event that the route is determined to not pass through a high-rise building area, establishes a tunnel as a property of the driving route data.

Description

[0001] This disclosure claims priority based on Japanese Patent Application No. 2012-223433 filed on October 5, 2012, and the content of the description is incorporated herein. technical field [0002] The present invention relates to a map information processing device for reflecting road information of a new road on map data when passing a new road, and a storage medium including a command for reflecting road information of a new road on map data. Background technique [0003] The car navigation device holds map data including road data, background data, etc., and uses the map data to display the position of the vehicle, search for and guide a route to a destination, and the like. However, road data of newly established roads may not be included in the map data. [0004] Therefore, a new road is detected by comparing the map data with the travel trajectory data, and an operation of adding road data of the detected new road to the map data is performed. In particular, in P...
